[hatari-devel] DSP host interface interrupted mode : help needed

Hello,

I've replied this to the DHS forum :


According to the falcon hardware documentation found on 
(http://dev-docs.atariforge.org/),

I can see that the Hreq pin going out of the DSP enters into the COMBEL 
chip (page 3 of the document).
(it's name is XNFPINT from DSP view and NFPINT from COMBEL view).

I haven't found this pin connected to the 68030.

If the COMBEL chipset is the MFP, it would mean that it's a MFP interrupt.

Any advise on this point ?

If so, we still don't know the priority level.

Regards,

Laurent
